T digital search system includes a server for receiving and processing the device location and heading information, and a filtering module for filtering a first group of places of interest to provide a first set of places of interest. The filtering module is programmed to: 1) receive at least one place of interest to form the first group of places of interest; 2) exclude places of interest having a location outside of a predetermined radial range from the device location; and 3) if the number of remaining places of interest exceeds a first predetermined quantity, exclude the places of interest having locations that are the greatest distance from the device until the number of remaining places of interest does not exceed the first predetermined quantity, whereby the first set of places of interest is provided. The system also includes a data file comprising at least one confirm count related to a point of interest, and a sorting module for receiving and processing the first set of places of interest to provide a second set of places of interest. The sorting module is programmed to: 1) receive the first set of places of interest; 2) order the places of interest based on the confirm count; and 3) if the number of places of interest exceeds a second predetermined quantity, exclude the places of interest that are ordered last according to step 2, until the number of remaining places of interest does not exceed the second predetermined quantity, whereby the second set of places of interest is provided.

In a preferred embodiment, the server is programmed to search for points of interest within the predetermined radial range from the device. Preferably, the server uses an API to search for points of interest within the predetermined radial range from the device. In a preferred embodiment, the sorting module is further programmed to sort the places of interest based on a category related to a point of interest.

In a preferred embodiment, the filtering module is further programmed to exclude points of interest having a location outside of a first triangle shaped range near the location of the device. The first triangle shaped range starts from the location of the device and spreads out away from the location of the device in the direction of the heading of the device. The first triangle shaped range spreads out at a first angle from the location of the device with respect to the heading of the device. The first triangle shaped range also extends a first distance from the location of the device in the direction of the heading of the device. In a preferred embodiment, the filtering module is further programmed to exclude points of interest having a location outside of a second triangle shaped range near the location of the device, wherein the second triangle shaped range starts from the location of the device and spreads out away from the location of the device in the direction of the heading of the device, and the second triangle shaped range extends further away from the location of the device than the first triangle shaped range. The second triangle shaped range spreads out at a second angle from the location of the device with respect to the heading of the device. The second triangle shaped range also extends a second distance from the location of the device in the direction of the heading of the device. Preferably, the second angle is less than the first angle and the second distance is greater than the first distance.

In a preferred embodiment, the system includes a software application executing on the device for transmitting the location and heading of the device to the server, receiving collected information transmitted from the server, and displaying the collected information to a user. Preferably, the software application provides a user interface, whereby the software application transmits the location and heading of the device to the server, receives collected information transmitted from the server, and displays the collected information in response to a single user interaction.

The digital search system includes a location-based retrieval module and an image-based retrieval module. The location-based retrieval module includes a location-based filtering module for filtering a first group of places of interest to provide a first set of places of interest. The filtering module is programmed to: 1) receive at least one place of interest to form the first group of places of interest; 2) exclude places of interest having a location outside of a predetermined radial range from the device location; and 3) if the number of remaining places of interest exceeds a first predetermined quantity, exclude the places of interest having locations that are the greatest distance from the device until the number of remaining places of interest does not exceed the first predetermined quantity, whereby the first set of places of interest is provided. The location-based retrieval module also includes a sorting module for receiving and processing the first set of places of interest to provide a second set of places of interest. The sorting module is programmed to: 1) receive the first set of places of interest; 2) order the places of interest based on the confirm count; and 3) if the number of places of interest exceeds a second predetermined quantity, exclude the places of interest that are ordered last according to step 2, until the number of remaining places of interest does not exceed the second predetermined quantity, whereby the second set of places of interest is provided. The location-based retrieval module also includes a data file that includes at least one confirm count related to a point of interest. The image-based retrieval module includes an image matching module for receiving and processing digital image files. The image matching module programmed to: 1) receive a digital image file; 2) convert the digital image file to a first data structure having at least one hash value; 3) search for hash values corresponding to images similar to the image in the digital image file; and 4) return a second data structure comprising results from the search in step 3. The image-based retrieval module also includes a filtering module for receiving and processing data structures. The filtering module is programmed to: 1) receive a third data structure comprising hash values corresponding to images; and 2) return a fourth data structure comprising metadata related to images to which the hash values in the third data structure correspond, but excluding metadata where the hash values in the third data structure correspond to an image having a location that exceeds a predetermined distance from the location of the device that captured the digital image file. The image-based retrieval module also includes one or more software routines executing to 1) search for images similar to that in the digital image file; 2) filter the results of the search in step 1; 3) generate the fourth data structure comprising metadata including a title related to the results of step 2; and The digital search system also includes a server for receiving and processing a digital image file and the location and heading of a device used to take the image in the digital image file. The server is programmed with one or more software routines executing on the server to: 1) simultaneously use the location-based retrieval module to generate the second set of places of interest based on the location and heading of a device, and the image-based retrieval module to generate the fourth data structure; 2) combine the second set of places of interest and the fourth data structure into a final results list; and 3) transmit the final results list to the device.

In a preferred embodiment, the digital search system also includes a software application executing on the device to: 1) take a photograph; 2) transmit to the server a digital image file comprising the photograph, the location of the device, and the heading of the device; 3) receive a list transmitted from the server; and 4) display the list to a user. Preferably, the software application provides a user interface, whereby the software application performs the steps above in response to a single user interaction. In a preferred embodiment, the user interface allows a user to confirm a result in the displayed list, and wherein the server increments the confirm count related to the result in response to the user's confirmation.

The present invention is directed to a system and method of providing place (e.g., business, landmark, statue, monument, landmark, building, hotel, restaurant, etc.) relevant information based upon a mobile device's location and heading information. Taking a picture of a landmark or business will return results of information for places related to the area and in proximity to the origination of the image. For example, multiple businesses and landmarks including names, descriptions and other related data may be provided as search results based upon the image's location, heading and/or range. In other words, the search criteria may be based upon the mobile device's location, heading and/or defined ranges at the time of the picture being taken by the mobile user. The user may help define the correct result by confirming a result as a match to the “place” within the picture. Future users who capture photos within that same general proximity will receive refined search results based upon past users' “place” confirmation matches to images. Over time the database query factors will provide users with an experienced sense of image recognition due to potentially more accurate results.

In a preferred embodiment, the present invention is comprised of a computer database for storing information, the database configured to store information relating to points of interest including businesses and landmarks, the database adapted to store for each point of interest the location of the point of interest, and its name; a server for receiving device location and heading information from a device used to take the photo, the server programmed with one or more software routines executing on the server to: 1) process the device location and heading information to search for points of interest within a predetermined range of the device location and heading; 2) collect information relating to the points of interest within the predetermined range of the device location and heading; 3) communicate the collected information relating to the points of interest to the device used to take the photo.

In a preferred embodiment, the server is programmed with one or more software routines executing on the server to search for points of interest within a predetermined radial range around the location of the device and conical shaped range near the location of the device. The conical range preferably starts from the location of the device and spreads out towards the direction of the heading of the device.

In one embodiment, the system is programmed with one or more software routines executing on the server to accept confirmations from users for points of interest communicated to the devices, to count the number of user confirmations for each point of interest, and to give the points of interest with the highest user confirmations the highest priority in the displayed results.

The system is also preferably configured to accept registrations from businesses and to allow registered businesses to offer deals. The server collects information relating to businesses nearby the predetermined range of the device location and heading that are offering deals to users and communicates the results to the device for display to the user.

Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, the drawings show a digital search system 100 in accordance with preferred embodiments of the present invention.

FIG. 1 illustrates a preferred embodiment of the present invention. In a preferred embodiment, there is provided a software application (90) running on a device (200), which is in communication with a server (220) via a network (210). In a preferred embodiment, the software application (90) transmits a digital image file (470) (see FIG. 14) to the server (220) via network (210). In a preferred embodiment, the server (220) comprises and uses both location-based retrieval logic or module (20) and image-based retrieval logic or module (30) in order to retrieve search results, which are then combined and returned to the software application (90) for display on the device (200). The results from image and location are compared and combined if there are duplicates. If there are no duplicates then image gets higher priority. Preferably, results received from the image-based retrieval module (30) will have higher priority than the results received from the location-based retrieval module (20) in the list of results that is returned to the device (200). However, the opposite can also be used. Those of ordinary skill in the art will also appreciate that in a preferred embodiment, server (220) may also use only one of either image-based retrieval module (30) or location-based retrieval module (20) to retrieve search results. In a preferred embodiment, the location-based retrieval module (20) uses a location-based filtering module (40), sorting module (60), and a data file (50). Preferably, the image-based retrieval module (30) uses an image matching module (70) and a filtering module (80).

FIG. 2 illustrates the data used by a first preferred embodiment of the present invention to retrieve place relevant information relating to a device (e.g., mobile device) of the user taking the photo. In a preferred embodiment, the present invention collects the device's current location (100), the device's heading (130), near/radial range (110), near/wide range (120), and far range (140). The location (100) is preferably determined using the device's GPS latitude and longitude.

FIG. 3 illustrates a preferred embodiment of the system of the present invention. FIG. 4 illustrates a flowchart showing some of the basic process steps of a preferred embodiment. In a preferred embodiment, a mobile device (200) communicates with a server (220) through a WiFi network or data Internet connection (210). Preferably, the server (220) collects the data from a database (230).

The mobile device (200) collects the device's current location (100) and the device's (200) heading (130)(240) which is adjusted based upon the device's (200) orientation then submits to the server (220)(260) the location (100), heading (130), near/radial range (110), near/wide range (120), and far range (140). Preferably, the location (100) is determined using the mobile devices (200) GPS latitude and longitude.

In a preferred embodiment, the heading (130) is determined by the device's (200) orientation and the direction that the camera is pointed. The near/radial range (110) is the circular 360 degree radius directly around the mobile device (200) with it acting as the center point based upon the location (100). The near/wide range (120) is the hard coded cone shaped distance reaching out from the device's (200) location (100) as the base of the cone. The far range (140) begins with the device location as the base of the point and stretches out to a further and thinner cone shaped zone distance than the near/wide range (120). It will be appreciated by those of ordinary skill in the art that the exact distances for each of these ranges can be varied as needed, as long as they are within a range of 1 to 6000 meters. For example, the ranges can be made smaller for more focused results and made larger for a wider range of results.

In a preferred embodiment of the present invention, after the collection of the location (100), near/radial range (110), near/wide range (120), heading (130), and far range (140), the device (200) communicates these data items to the server (220), preferably via a network connection (210)(260). In a preferred embodiment, the server (220) queries the database (230) for points of interest related to the location (100), heading (130) and range (110, 120, 140) criteria (280).

In a preferred embodiment of the present invention, the server (220), and associated processing system, and database (230) system will determine the relevant points of interest based upon 5 factors and present them to the user (300). These points of interest determining factors are sorted based upon a priority level with the highest level factor being more relevant to the user's experience. These preferred factors, with the highest factor listed first are:

1. Business with confirm count>0 (highest to lowest) (0-500 meters from location);

2. Locations with Wikipedia OR Factual category “Landmark” AND confirm count>0 (Highest to lowest) (0-3200 meters);

3. Businesses with confirm count-0 (0-500 meters);

4. Locations with Wikipedia OR Factual category “Landmark” AND confirm count-0 (0-3200 meters);

5. Businesses with Deals (500-3200 meters) sorted by confirm count (Highest to lowest).

In a preferred embodiment, a confirm count is the sum of all users that previously identified a “place” search result as a business or landmark that they were taking a picture of. For example, if a user takes a picture of Alcatraz Island and the results are returned with the Golden Gate Bridge listed first, the user would likely go to the next search result without confirming the result because the Golden Gate Bridge does not match the user's expectation. If the next result is Alcatraz, the user would likely press the “confirm” button displayed by the present invention (in association with the search result) to confirm (i.e., identify) the Alcatraz search result as the place that was the focal point of the user's photo and as the result the user expected.

If within that same general area 100 users take pictures and 70 of them confirm the Alcatraz search result, then the first result listed will be Alcatraz (assuming it has the highest confirm count). If, over time, 500 users take a picture within that same general area and 350 confirm the Golden Gate Bridge search result, and the confirm count for Alcatraz only increased to 100 confirms, then the first result listed by the present invention will now be the Golden Gate Bridge search result. This feature of a preferred embodiment of the present invention allows the users to drive the experience by identifying what they expect as the returned result from their photo. In the preferred embodiment, the server of the present invention will record these confirms and run a calculation after every user photo to then display the sorted results based upon the up-to-date confirm counts.

The first preferred factor queries the database for all points of interest (e.g., business and/or landmark listings) within the database (230) containing a confirm count of greater than zero and that are located within the defined location (100), heading (130) and range (110, 120, 140) and that are no greater than 500 meters from the device's (200) exact location (100). Factor one results are sorted by highest to lowest confirm count. Again, those of ordinary skill in the art will appreciate that the distance of 500 meters can be changed to any distance within the range of 1-6000 meters based on the desired level of focus.

The second preferred factor queries the database (230) for all points of interest listings with a confirm count greater than zero and that are located within the defined location (100), heading (130) and range (110, 120, 140) and that are no greater than 3200 meters from the device's (200) exact location (100). Factor two results are sorted by highest to lowest confirm count. Specifically, in one example embodiment, the server (220) receives content from a third party database or service such as Wikipedia and/or Factual to search for relevant points of interest within the range of the device. For example, the server (220) of a preferred embodiment calls the Wikipedia API and Factual API to receive content from their databases for latitude and longitudes that reside within the three location/heading defined ranges. That content is then pulled into the database (230) that can be queried for relevant points of interest based upon the search priority list discussed above. For places that exist within the database of the present invention, the Wiki content is preferably merged to those places as the description content. In another preferred embodiment, the server (220) can call into the third party services (APIs) or databases and conduct a direct query of those third party databases to retrieve relevant points of interest to merge into the content of the system database (230).

The third preferred factor queries the database (230) for points of interest listings with a confirm count equal to zero and that are located within the defined location (100), heading (130) and range (110, 120, 140) and that are no greater than 500 meters from the device's (200) exact location (100). Factor three results are sorted by highest to lowest confirm count.

The fourth preferred factor queries the database (230) for points of interest listings with a confirm count equal to zero and that are located within the defined location (100), heading (130) and range (110, 120, 140) and that are no greater than 3200 meters from the device's (200) exact location (100). Factor four results are sorted by highest to lowest confirm count.

The fifth preferred factor queries the database for points of interest listings that contain deals and that are located within the defined location (100), heading (130) and range (110, 120, 140) and that are between the distance of 500 to 3200 meters from the device's (200) exact location (100). Factor five results are sorted by highest to lowest confirm count. Deals are defined as discounted promotions that are generated and published to the database by the business for the purpose of incentivizing the user to become a customer of that business. The server (220) then preferably communicates the points of interest to the mobile device (200) via a network internet connection (210).

In a preferred embodiment, image recognition may be used as part of the process of retrieving relevant search results. For example, image recognition could be added as the first item to the search priority list. The priority given to the image recognition is dependent on the accuracy of the image recognition. If it is extremely accurate then it should receive priority but if it is less accurate than it should receive a lower priority. It is also appreciated that image recognition may work better as a hybrid blended into each method on the priority list. E.g., add image recognition as a requirement to each existing item within the priority list. Image recognition results can also be categorized outside of the current 5 step classification where the results are presented to user as a separate category of results.

In a preferred embodiment, information relating to a place that was recognized are preferably retrieved and presented to the user, along with relevant data including, but not limited to, name, address, telephone number, photos of the point of interest, history, facts, shared photos, tours, attractions, top places nearby and user reviews. It is also appreciated that advertisements relating to the business may also be displayed. E.g., a business can register with the system of the present invention to provide deals within the application. For example, if a user creates a deal for business XYZ, then that deal is displayed within the ad tile presented by the present invention for business XYZ.

Separately, the last item within the search priority list may also refer to businesses that have ads but do not match the requirements of the other search priority list items. Those businesses will display last within the search results and are there to act as impressions only because they most likely don't match the user's photo. Nearby places preferably consist of ads placed by registered businesses that have defined category(s). For example a business can create an ad and define categories for the ad. If the business is nearby, their ad can show in “Nearby Places” of other locations that are of a matching category defined within the ad.

FIG. 13 illustrates an exemplary screenshot of the present invention illustrating the deals detail screen where the user can redeem their deal (450, also shown in the Figure at reference numeral 12) at the business by scanning the application QR code at the counter.

FIGS. 14-16 show a preferred embodiment of the location based retrieval module. As shown in FIG. 14, depicting the operation of a preferred embodiment of the present invention, the server (220) receives the device location (100) and location heading (130) from the device (200). In a preferred embodiment, a user uses the software application (90) executing on the device (200) to take a photo and the software application (90) generates (470) and optimizes (480) a digital image file. In a preferred embodiment, the software application executing on the device optimizes digital image file (470) (480) by reducing the size of the digital image file (470). In a preferred embodiment, the server (220) receives a digital image file (470) from a device (200). Preferably, the server (220) then processes the device location and device heading. In a preferred embodiment, the server (220) then collects (490) information including locations relating to points of interest within a first predetermined distance from the device location. In a preferred embodiment, the server (220) searches for points of interest within a first predetermined distance from the device location by transmitting the device location coordinates to at least one application programming interface (API). In a preferred embodiment, the first predetermined distance is between 10 meters and 6000 meters. In a more preferred embodiment, the first predetermined distance is between 1000 and 4000 meters. In a most preferred embodiment, the first predetermined distance is about 3,200 meters. In a preferred embodiment, such APIs include one or more of APIs provided by Foursquare, Wikipedia, Factual, Viator, Uber, Trip Advisor, Flikr, Fandango, IMDB and Yelp. It will be understood by one of ordinary skill in the art that the use of the aforementioned APIs is merely exemplary and that in a preferred embodiment other APIs, including an API provided by the digital search system itself, can be used to search for points of interest. The results of a search on one API can be run against the results of any other API

FIG. 15 depicts the logic for performing the search (490) using the FourSquare API in a preferred embodiment of the present invention. As shown in FIG. 15, the device location is at the center of bubble 1 having a first radial distance (500). Preferably, the server sends a search request to the FourSquare API with the device location (100) and requesting all results within the first radial distance (500) from the device location (100) (referred to herein as the “first location”). The server then adjusts the location in the direction of the device heading (130) by a distance equal to the first radial distance (500) plus a second radial distance (510), which is larger than the first radial distance, to a second location (as indicated by 520). The server (220) then sends another search request to the FourSquare API with the second location (520) and requesting all results within the second radial distance (510) of the second location (520). Preferably, the search results will be added to the list of results from the prior search of the FourSquare API. Those of ordinary skill in the art will appreciate that the use of this process in a preferred embodiment to search the FourSquare API is merely exemplary and this process could be used to search any other API or service. Those of ordinary skill in the art will appreciate that this process can be repeated until a satisfactory number of search results are collected or until the server (220) has searched satisfactory distance from the original device location (100) (see, e.g., bubbles 3 and 4 in FIG. 15).

In a preferred embodiment, the digital search system can search for points of interest by executing a search against a database, files, or an index. Returning to FIG. 13, in a preferred embodiment, the search returns a data structure comprising information relating to points of interest. Preferably, the points of interest include businesses. It will be appreciated by those of ordinary skill in the art that points of interest can include landmarks, monuments, parks, outdoor features, geographical features, and the like.

It will be appreciated by those of ordinary skill in the art that other information relating to points of interest may also include metadata, ratings, reviews, images, descriptions, categories, tags, or any other information that may be related to a point of interest.

In a preferred embodiment of the present invention, the server (220) then filters the data structures comprising collected information relating to points of interest (530) (referred to herein as an “angel search” based on the shape shown in FIG. 16). Preferably, for each source (including APIs) returning results in response to the search described in the paragraph supra, the server filters the data structures received from each source.

FIG. 16 depicts the “angel search” filtering logic used by a preferred embodiment of the present invention. As shown in FIG. 16, in a preferred embodiment, the server (220) uses a location-based filtering module (40) (see FIG. 1) programmed to: 1) receive at least one data structure; 2) exclude data structures having a location outside of a predetermined near/radial range from the device location (100); 3) exclude data structures having a location outside of a first triangle shaped range (540) near the location (100) of the device, wherein the first triangle shaped range (540) starts from the location of the device (100) and spreads out toward the direction of the heading of the device (130); 4) exclude data structures having a location outside a second triangle shaped range (550) near the location (100) of the device, wherein the second triangle shaped range (550) starts from the location of the device (100) and spreads out toward the direction of the heading of the device (130); and 5) if the number of remaining data structures exceeds a first predetermined quantity, exclude the data structures having locations that are the greatest distance from the device until the number of remaining data structures does not exceed the first predetermined quantity. Preferably, the near/radial range will be a circle around the device location (100) having a radial distance (560) of about 10 meters. However, those of ordinary skill in the art will appreciate that the radial distance (560) can be a circle around the device location (100) with a radius of between 1 to 100 miles. More preferably, the radius is between 1 meter and 10 miles. Most preferably, the radius is between about 1 and 1000 meters. In a preferred embodiment, the first predetermined quantity is within the range of 5-100. In a more preferred embodiment, the first predetermined quantity is within the range of 10-50. In a most preferred embodiment, the first predetermined quantity is 20. Preferably, and as shown in FIG. 16, the first triangle shaped range (540) includes a first line 542 generally perpendicular to the device heading 130 that intersects the device heading 130 at a second distance (570) from the device location (100). The first triangle shaped range (540) also includes second and third lines (544) and (546) that extend outwardly from the device location (100) at an angle (590) from the device heading 130. Likewise, in a preferred embodiment, the second triangle shaped (550) includes a first line 552 generally perpendicular to the device heading 130 that intersects the device heading 130 at a second distance (580) from the device location (100). The second triangle shaped range (550) also includes second and third lines (554) and (556) that extend outwardly from the device location (100) at an angle (600) from the device heading 130. It will be appreciated by those of ordinary skill in the art that preferably, the second distance (570) and third distance (580) may be any positive distance within the range of 1 meter to 100 miles. Those of ordinary skill in the art will appreciate that the filtering module can be either software or a component of software executing on the server, or located on another server or machine.

Returning to FIG. 14, in a preferred embodiment of the present invention, the server (220) then again searches for matches against the various sources using the filtered information (610 and 620). By way of non-limiting example, in a preferred embodiment, the information received from the Wikipedia API and then filtered is sent to the FourSquare API (620). Likewise, in a preferred embodiment, the information that was received from the FourSquare API and filtered would be sent to the Wikipedia API (610). In a preferred embodiment, location names are used to search another source or API for matches. Preferably, any matches returned from the APIs are saved to a list. As shown in FIG. 14, in a preferred embodiment, if the number of results from Wikipedia is greater than 0, then a number of results from the search of the Factual API are added to a list. Otherwise, preferably, if the number of results from the first searches of Wikipedia and FourSquare is 0, then results from the search of the Factual API are saved to a list until the list contains the predetermined number of results (640). In a preferred embodiment, the list of results from the Factual API is then used to search the Wikipedia API and the results of this search are added to a list (650). Preferably, the location name will be used to search for matches. Those of ordinary skill in the art will appreciate that the described use of specific APIs in a preferred embodiment is merely exemplary and any specifically named API can be replaced by another API or search service.

In a preferred embodiment of the present invention, the server (220) then sorts the lists of collected information into an aggregated list 660. Step 660 is performed by a sorting module (60) programmed to: 1) receive at least one data structure; 2) order the data structures based on at least a confirm count related to a point of interest; and 3) if the number of data structures exceeds a second predetermined quantity, exclude the data structures that are ordered last according to step 2 until the number of remaining data structures does not exceed the second predetermined quantity. Preferably, the confirm count related to a point of interest will be stored in a data file (50) accessible to the server (220). In a more preferred embodiment, step 2, which is performed by the filtering module orders the locations according to the following order: 1) businesses with a confirm count greater than zero and within a first predetermined distance from the device location; 2) locations with a confirmation count greater than zero, having a Wikipedia or Factual category of “Landmark,” and located within a second predetermined distance from the device location; 3) businesses with a confirm count of zero and within the first predetermined distance from the device location; 4) locations with a confirm count of zero, having a Wikipedia or Factual category of “Landmark,” and located within the second predetermined distance from the device location; and 5) businesses having deals and located within the region between the first predetermined distance from the device location and the second predetermined distance from the device location, further ordered by greatest to least according to confirm count. In a most preferred embodiment, the second predetermined quantity is about 20, the first predetermined distance is about 500 meters, and the second predetermined distance is about 3200 meters. However, those of ordinary skill in the art will appreciate that these predetermined values are merely exemplary and any positive value can be used. Those of ordinary skill in the art will also appreciate that the described use of specific APIs in a preferred embodiment is merely exemplary and any specifically named API can be replaced by another API or search service. Those of ordinary skill in the art will further appreciate that the use of the “Landmark” category as a factor by which search results are ordered is merely exemplary and that any category can be used to sort the search results.

As shown in FIG. 14, in a preferred embodiment of the present invention, the server (220) then sends the sorted list of information to the device (200).
